Climate change is reshaping the legal landscape at every level of government. Kaplan Kirsch is a national law firm that helps public and private sector clients turn ambitious climate commitments into durable legal outcomes—in legislative chambers, regulatory proceedings, and courts across the country.
Effective climate policy begins with well-crafted laws. Kaplan Kirsch advises clients on fast-moving climate legislation at the state and federal levels. We develop legislative strategies, analyze proposed bills, and draft statutory language designed to achieve impactful outcomes. We work alongside legislators, advocacy organizations, municipalities, and industry stakeholders to advance climate laws that are legally sound and politically durable. Our legislative work has helped shape some of the most forward-looking climate statutes in the nation.
Strong laws, however, only take effect through rigorous rulemaking. Our attorneys guide clients through every stage of the administrative policymaking process—from early comment strategy to final rule publication. We draft proposed rules and regulations, develop policy solutions, and ensure that agency rulemakings reflect the strongest possible climate protections. The greenhouse gas (GHG) rules and climate standards we have helped shape often serve as national models for jurisdictions around the nation.
Those rules, in turn, must be defended. Bold climate action is rarely uncontested. Kaplan Kirsch litigates on behalf of clients who need to defend climate regulations and challenge agency rollbacks. We also hold polluters and regulators accountable for failing to act. Our attorneys bring a sophisticated command of constitutional law and the Clean Air Act (CAA). We are well-versed in the federal and state environmental statutes implicated by climate change litigation. We have successfully represented clients in federal and state courts and administrative forums.
Kaplan Kirsch built its climate practice over decades of consequential work. We operate at the intersection of environmental law, energy policy, and public advocacy. Our attorneys have counseled leading environmental organizations, state and local governments, utilities, and clean energy developers on the legal dimensions of decarbonization—from setting GHG emission reduction targets to defending those targets in court. We have filed amicus briefs in high-profile environmental cases, participated in landmark rulemakings, and provided testimony that has informed climate legislation at multiple levels of government. We’re more than advisors for climate change law—we help write it, defend it, and enforce it.
